Well, finally I can clearly affirm, this is not for me. Last attempt and unsuccessful. I would say that in 4 years I've prepared around 8-10 brews, and only three where psychoactive (which different levels of potency), but no one could compare with 3g of mushrooms and specially with 3.5g + lemon tek. A bit disappointed with it... But nevertheless a non effective brew can always happen and it was an interesting experience to try to emulate the "ayahuasqueros".
That was my recipe:
1. Let it rest one week in the jar with mineral water. 4.5g of seeds and 10g of MHRB (of course, separatedly).
2. Filter, keep the liquid in the same jar, and boil the remains with two big spoons of apple vinegar until reduction. Then add the remaining liquid to the previously filtered one.
3. Just to be sure although this is probably unnecessary, let it rest for another week.
4. Filter and reduce.
No tanin removal was done for the mimosa, just like that (and tasted horrible. I have goosebumps and nausea if I remember it).
For the syrian rue I add 3.5g of gelatine to ca. 200ml of syrian rue and let it rest in the fridge until it got solid. Despite of this idea it was also horrible to eat, but thanks god not so compared to drink. Cutted in tiny pieces and with some water one could just gulp it like a pill, although it may take 10 minutes to finish.
I've waited 45 minutes to have the effects of the harmalas, and then was time to drink the mimosa. As it tasted very disgusting, I've filtered about 1/3 of the glass (the other 2/3 were already drunk) and in the coffee filter was present a lot of dusty parts, like black sand (yugh). I add also some mineral water to reduce the contentration and make it a bit palatable. Two gulps, and done, then time to use some honey and mouthwash to disipate the flavour.
Some effects appeared about T + 1:30, like feeling a bit dizzy, some tinitus, feeling weak but relaxed, a good feeling of peace although with some nausea from time to time, kind of blurred vision, but nothing more. I turn the room into "pitch black" and closed my eyes, but nothing. As I felt my stomach a bit upside down, I tried to force the vomit a few times (even by touching the throat with the fingers), but nothing came out. I then waited to T+3:00 before braking my fast of >10h and considering this experiment as done.
Apparently the gelatine shouldn't be a problem as in some forums I've read it has worked (also by using gelatine in both! Mimosa too!) while others said it make them puke a lot. As from my point of view the harmalas did they work, I blame this result on following things; or the mimosa is not strong enough (would say so, also had more than 4 years), or the timing was wrong scheduled, or the recipe was wrong, or why not, all of them.
Now I don't have any ingredient left so I can't prepare another brew, but do you have any advice for me for the future?
